A breakthrough infection is defined as when a fully vaccinated individual still gets COVID-19 if they are exposed to SARS-CoV-2.
It turns out that pregnant people who are vaccinated against COVID-19 are nearly twice as likely to get a breakthrough infection as those who are not pregnant, according to the study.
Authors of the study reviewed nearly 14 million medical records of patients who suffer from various co-morbidities—from liver disease to mental health issues—and deduced risks of contracting COVID-19 when fully vaccinated. It was found that pregnant women were linked with the highest risk.
“Pregnant individuals are 1.91 times more likely to have a breakthrough infection, individuals with a solid organ transplant are 1.83 times more likely, and individuals with an immune system deficiency are 1.63 times more likely,” the authors of the study wrote.
“If you are fully vaccinated and become pregnant, you remain at higher risk of acquiring COVID.”
